The invention relates to a fibre container, and particularly to a'fibrecontainer provided with a metal part with which the container closure orother means may cooperate for securing the closure to the container.

An object of the invention is to provide a fibre container which willhave all of the effectiveness and adaptability of a metal container for.closure application, attachment and sealing.

Another object of the invention is to provide a fibre container having aclosure anchoring part which is located entirely on the exterior of thecontainer, and may be eflectively secured to the walls of the containerwithout the useof fastening means piercing the fibre.

vide a fibre container having a metal closureanchoring part providedtherein,- in-which said The invention possesses other objects andfeatures of advantage some of-which, with the foregoing, will be setforth in the following description of the preferred form of theinvention which is illustrated in the drawings accompanying and formingpart of the specification; It is to be understood, however, thatvariations in the showing made by the said drawings and description maybe adopted within the scope of the invention as set forthin the claims.

Referring to said drawings:

Figure l is a fragmentary side view of a container constructed inaccordance with the-present invention, portions being removed todisclose hidden parts.

Figure 2 is a full longitudinal sectional view of the container as shownin Figure 1.

Figure 3 is an enlarged fragmentary detail of a portion of the containershown in Figure 2. Figures 4 and 5 are views similar to Figure 3 butshowing somewhat modified arrangements. In the embodiment of theinvention hereillustrated, the container is formed with cylindrical sidewalls 6 preferably made up of laminations I of fibre or the like. At anend of the walls is provided an opening I arranged to be covered by aclosure 9 which, as shown in Figures 2 and 3, is made up of laminatlonsI! of material 55 Foriastening or looking the closure 0 in opersimilarto the laminations 1. The cover in i formed with an inset body portionII and an annular skirt M which extends from the edge of'the body I! andis arranged to engage the '5 portion it of the inner side of the wallsI, it

being thus noted that since the portion II is a part of the fibre wallof the container, a more or less yielding seat for the closure will beprovided.

10 To form'a means on the walls of th container l5 embraces thecontainer on the exterior side of A further object of the invention isto prothe walls 6 adjacent the opening. The outer longitudinal portionof the band I1 is extended first radially outwardly thencelongitudinally inwardly and thence radially inwardly to form a 'm curlor roll ll lying radially outwardly 01 what may be termed thebodyportion it Desirably the outward longitudinal part II of the seat Itis fiared radially outwardly corresponding to the adjacent portion orthe band, and is gradually 2! reduced in section so. that said part 2iwill curve over and mergeinto the curl it. This construction provides asmooth, protected, and reinforced rim for the container at the opening.and at the same time facilitates the ready and proper insertion of theclosure in its seat. It

desired, the longitudinally outer part I! of the skirt may be flared andtapered in correspondence with the part 2| of the-container walls, andis preferably extended so as to fit well over said Part ii. v

For securing the band on the walls against longitudinal displacement inopposite directions, there is rolled or otherwise depressedinto the sideof the walls I, an inwardly offset portion It completely around thecontainer, and pref- 'erably such oifset is fitted or extruded into aroove 24' provided in the outerside of the walls and desirably formedtherein simultaneously with 4 the oifset II. As an additional means offasten- 4s ingthe band and 'container together, a film of water -proof'glue is interposed between the D- posing surfaces of the band andcontainerthrwghout the-entire area or engagement. It may be noted thatthe lip or part II also assists to in locking the band in position, andpreferably the longitudinally inner edge 28 is crimped inwardly into thewall stock as a further attachment for the band and to present a smoothsurface at the luncture of such edge and the walls.

body 01. the band, Desirably the portionljfl, of. the ring and a' partof the contiguous portion araaiaara ranged toengage the curl, is slittedso as to provide a plurality of tongues 29 and thus permit the moreready application of the ring over the closure and container parts andthe removal of the ring from engagement therewith.

If de t e c n ln r' f my in e n flared portion corresponding to andembracing the flared Portionof said wall, said band being he used with ametal closure-3i such as shown jacent said end and having an annularouter portion forming a curl positioned radially outwardly from saidwalls and adjacent said open end, a closure fitting within said seat andhaving a portion extending therefrom and overlying but not encirclingsaid curl, and means independent of said closure and band securing saidclosure to the curl. 1
